Preparation and photochemical reactivity of poly(styrene-co-vinylbipyridine) pendant Ru(bpy)/sup 2 +//sub 3/ complex
- Inst. of Physical and Chemical Research, Wako-shi, Japan
Tris(2,2'-bipyridyl)ruthenium(II) complex (Ru(bpy)/sup 2 +//sub 3/) is attracting much attention as sensitizer for water photolysis with solar irradiation. In order to construct a photochemical conversion system, the utilization of a heterogeneous reaction has been considered to be important. The incorporation of the complex into molecular assembly such as micelle or liposome is one approach to this subject. The present authors have prepared the polystyrene pendant Ru(bpy)/sup 2 +//sub 3/ and constructed a photoinduced electron relay system at the solid-liquid interface composed of the polymer complex and the solution of methylviologen. Preparation of various kinds of polymer pendant Ru(bpy)/sup 2 +//sub 3/ must lead to many possibilities of constructing photoenergy conversion systems. For this purpose, 4-methyl-4'-vinyl-2,2'-bipyridine (Vbpy) was copolymerized with various vinyl monomers. In this article the preparation and photochemical behavior of a polymer pendant Ru(bpy)/sup 2 +//sub 3/ based on the copolymer of Vbpy and styrene are described.
